This is a problem for novices on how to hold the camera steadily.
The correct posture is: place your thumb on the back of the camera and bend the other four fingers away from the edge of the lens (or at the edge of the camera) Pinch the camera part). Then bend your arms, place your elbows just on the side of your chest for support, and use your legs to stand in a figure-eight shape.
Use your arms as support with your hands on the side of your chest, and use your arms to support your upper body with your legs in a figure-eight shape. For support, form a stable angle frame.
Then there is the problem of pressing the shutter: try to only use the second joint of the right index finger to remove the shutter, otherwise it will easily cause the camera to shake, which takes time Go practice. If you have a high level of understanding, you can hold the camera steadily with one hand in 1/30 of a second.
Finally, I wish you success!
